Problems solved by technology

[0003] Diamond saw blades are mostly used in the actual cutting process. The main performance indicators of diamond saw blades include high strength, wear resistance, and corrosion resistance. The current technology has basically solved the problem of corrosion resistance, but However, there are big problems in strength and wear resistance, which lead to short service life of diamond saw blades and affect the cutting effect. To solve the problem of strength and wear resistance of diamond saw blades, we must not only start from its raw material formula, but also It is important to improve its production process, as well as the various equipment used in the production process, are direct factors affecting the performance of diamond saw blades, and according to the existing diamond production process, there are still many problems that need to be improved. aspect

Embodiment 1

[0037] Embodiment 1: High-strength continuous tooth diamond saw blade, the continuous tooth diamond saw blade includes main materials according to the volume fraction: diamond 12%, copper 26%, iron 40%, tin 6%, nickel 5%, cobalt 8% and auxiliary materials Alloy powder 3%.

[0038]The high-strength continuous-tooth diamond saw blade hot-press forming process includes the following steps:

[0039] (1) Ingredients: select the main materials diamond, copper, iron, tin, nickel, cobalt and alloy powder according to the volume fraction ratio, and reserve;

[0040] (2) Pre-mixing: Pre-mixing mechanism 1 is used to mix iron and cobalt for 40 minutes. After the iron and cobalt are mixed, add the remaining diamond, copper, tin and nickel from the feeding equipment of the pre-mixing mechanism at the same time. As well as alloy powder, the feed rate of copper is set to twice the feed rate of diamond, and the pre-mixing time of dry material is 6h;

[0041] Such as figure 1 As shown, a pl...

Embodiment 2

[0056] Embodiment 2: High-strength continuous-toothed diamond saw blade, the continuous-toothed diamond saw blade includes main materials according to the volume fraction: 15% diamond, 20% copper, 42% iron, 3% tin, 10% nickel, 5% cobalt and auxiliary materials Alloy powder 5%.

[0057] The difference with the technique of embodiment one is:

[0058] (2) Pre-mixing: Pre-mixing mechanism 1 is used to mix iron and cobalt for 35 minutes. After the iron and cobalt are mixed, add the remaining diamond, copper, tin and nickel from the feeding equipment of the pre-mixing mechanism at the same time. As well as alloy powder, the feeding speed of copper is set to 1.5 times of the feeding speed of diamond, and the pre-mixing time of dry material is 5.5h;

[0059] And the blanking opening diameter of a transition funnel 4 at the lowermost end in the feeding trough of copper is set as 1.5 times of the blanking opening caliber size of a transition funnel 4 at the lowest end in the diamond f...

Embodiment 3

[0069] Embodiment 3: High-strength wear-resistant diamond saw blade 12, the diamond saw blade 12 includes main materials according to the volume fraction: 15% diamond, 20% copper, 42% iron, 3% tin, 10% nickel, 5% cobalt and auxiliary materials Alloy powder 5%.

[0070] The difference with the technique of embodiment one is:

[0071] (2) Pre-mixing: Pre-mixing mechanism 1 is used to mix iron and cobalt for 30 minutes. After the iron and cobalt are mixed, add the remaining diamond, copper, tin and nickel from the feeding equipment of the pre-mixing mechanism at the same time. As well as alloy powder, the feed rate of copper is set to 1.5 times of the feed rate of diamond, and the pre-mixing time of dry material is 5h;

Abstract

The invention discloses a high-strength continuous-tooth diamond saw blade and a hot press molding technology thereof. The continuous-tooth diamond saw blade comprises the following main materials according to volume fractions: 12-15% of diamond, 20-26% of copper, 40-42% of iron, 3-8% of tin, 5-10% of nickel, 5-10% of cobalt and 3-5% of alloy powder as an auxiliary material. A method for producing the continuous-tooth diamond saw blade comprises the following steps: batching, pre-mixing, total mixing, cold press pre-molding, hot press sintering, primary cooling, high-frequency welding, secondary cooling, surface treatment, paint spraying, edging and the like. The strength and the wear resistance of the diamond saw blade which is produced by the formula and the technology of the invention are improved, in an actual using process, the service life is prolonged, the production cost is greatly saved, resources are saved, and moreover, the technology is environmentally friendly, sanitary and safe in a production process.

Description

technical field [0001] The invention relates to a diamond saw blade, in particular to a high-strength continuous-tooth diamond saw blade hot-press forming process. Background technique [0002] Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics. Diamond saw blades are mainly composed of two parts; the base body and the cutter head. The substrate is the main supporting part of the bonded cutter head, while the cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the substrate will not. The reason why the cutter head can cut The role of diamond is because it contains diamond, which is currently the hardest substance, and it rubs and cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head. [0003] Diamond saw blades are mostly used in the actual cuttin...
